Religion is a Latin word that means "piety, holiness".  Religion talks about the essence of human life. Religion is one of the sources of ethics. All religions have their own ethical ideas. And they are directed to improving moral and society. World religions are Buddhism, Christianity and Islam. The moral views of these religions play an essential role in the spiritual life of mankind.

Buddhism. The moral teachings of Buddhism are based on seven requirements: kind thoughts, kind words, kind behavior, kind manners, kind relations, goodwill, and a kind profession.  The ideal of Buddhism is not to harm people, nature and the world. The wisdom of Buddha says:

• The biggest enemy of a person is himself.
• To understand everything is to forgive everything.
• The most enormous sadness in a person's life is envy.
• The biggest mistake in life is to lose yourself.
• You will not be punished for your anger; you will be punished with your anger.
• When the mind is clear, joy follows you as a shadow and never leaves you.
• Don't spread gossip. Gossip is negative. If a person has heard negative, should keep quiet about it. Don't pass on negative energy further.
• Don't moralize others. Wisdom is spiritual energy. Share it only when the person needs a spiritual guide.
• Don't talk about your limitations. There is no point in telling others about shortcomings. It shows the weakness of a person, and decreases his spiritual energy.
• Don't talk about relationships. It is about friendship, love and work. If more talk about them, they get worse. If a person does compliment on something, it will change for the worse.
• Do not talk about perspective. In order not to break the plan, do not talk about it.
• Do not be proud of your own achievements. Do not joy for success and do not belittle others. Everything in this life can change.
• Do not shout with good deeds. Silence is gold. A person does not be sad about people and situations: they are powerless without your reaction.
• Kindness is medicine for your soul. A person does not need to talk about it. Because all kind deeds will be rewarded someday.
• Do not wait for gratitude and remember with good positive energy get bigger.
• Do not take negativity to heart. If a person does not accept the negative, it stays with the one who brought it. Pride is man's first sin.
• A person should relate with the love and mercy for all living beings. Love is active and selfless, it unit people.
• It is necessary to evaluate morality by deeds, not by words.
• Life is passing fast and nothing about it makes sense. Our joys and sadness are unimportant: today we feel bad, and tomorrow it will be good. We should not cry with emotions. Be calm as a flower.
• Only our soul remains with us, and all material things bring trouble and pain. Less attachment to material things means less pain.
• Do not try being better than someone, develop yourself spiritually. Do not keep evil. Anger destroys us from the inside, so it harms us much more than the enemy. The best quality is forgiveness. Control your actions. Each action of humans has results for the Universe because we are all part of its organism. What we give what we get - everything is simple.
• Live here and now. Everything has an end. In suffering from a past and worrying about a future, a sense of life is not lost. Get a little happiness just at the moment.
• Be thankful for things which you have. Be glad and enjoy what is around you.
• Everything changes. We easily lose what we love if it is not hidden within us. Any change should be accepted with thankfulness.
• Only your inner world is real. Every material thing has only the value that we give to it. The real world is in the human soul. We should cultivate it as a magic garden.
• Listen to your heart. It is important to listen to yourself, and follow your heart. All barriers are only in our heads! We are formed from our thoughts. We become what we think about.
• Getting angry is keeping hot coal in hand, planning to throw it at someone; he, first of all, burns himself.
• We are born again every morning. Only what you are doing now has real meaning.
• Happiness depends on what you think. Hate cannot destroy hatred; only love can kill hate and it is an eternal law. Pain is inevitable. But suffering is everyone's personal choice. Win yourself and you will win thousands of battles.
• There is no fire in the world more powerful than passion, more cutting than hate, and a big tornado (or hurricane) than greed.
• Do not be afraid of what will happen to you, your future will not change from this, but the present will become calm.
• There are five prohibitions of Buddhism: do not kill a living being, do not take another's thing, do not come close to someone's wife, do not tell lies, and do not drink alcohol. Christianity. In Christian philosophy, a human is an existence between angels and animals. According to Christian ethics, moral development is a reflection of the divine property in person. The ethical ideas of Christianity are as follows:

• Love brotherly each other with tenderness.
• Be glad for those who are glad and cry with those who cry.
• Stand up before the older person and honour the old man, and be afraid of your God.
• If a person thinks that he knows something, he does not know anything as well as he should know.
• The wise person should not demonstrate his wisdom, a strong person should not demonstrate his power or strength, and a rich person should not demonstrate his wealth.
• Wisdom is better than richness. The beginning of wisdom is the fear of the Lord.
• Wisdom is cleanness, calmness, modesty, and mercilessness to evil.
• If anyone misses wisdom, ask God, who gives everyone simply and without rejection.
• Whoever loves God has been given knowledge from Him.
